A probable case of vertical transmission of Onchocerca volvulus microfilariae.

A probable case of vertical transmission of Onchocerca volvulus microfilariae in Dass Bauchi State, Nigeria is presented. A 28-week-old male child delivered by a 39-year-old Fulani woman suffering from onchocerciasis was positive for O. volvulus microfilariae based on skin snip examinations. The child had general body pruritic rash and intermittent fever. Although the child's skin snip on re-examination five weeks later was also positive, the fever had gradually subsided.
